From 61b2c94d9e64758e55730be6a3fc9006c171db85 Mon Sep 17 00:00:00 2001
From: Gil Pitney <gil.pitney@linaro.org>
Date: Tue, 28 Oct 2014 18:00:42 -0700
Subject: Initial Commit:  Based on TI OpenCL v0.8, originally based on clover.

This is a continuation of the clover OpenCL project:
        http://people.freedesktop.org/~steckdenis/clover

based on the contributions from Texas Instruments for Keystone II DSP device:
        git.ti.com/opencl

and adding contributions from Linaro for ARM CPU-only support.

See README.txt for more info, and build instructions.
